<a name="gtk-Drag-and-Drop.description"></a><h2>Description</h2>
<p>
GTK+ has a rich set of functions for doing inter-process
communication via the drag-and-drop metaphor. GTK+
can do drag-and-drop (DND) via multiple protocols.
The currently supported protocols are the Xdnd and
Motif protocols.
As well as the functions listed here, applications
may need to use some facilities provided for
<a class="link" href="gtk-Selections.html" title="Selections">Selections</a>.
Also, the Drag and Drop API makes use of signals
in the <a class="link" href="GtkWidget.html" title="GtkWidget"><span class="type">GtkWidget</span></a> class.

<p>
Sets a widget as a potential drop destination, and adds default behaviors.
</p>
<p>
The default behaviors listed in <em class="parameter"><code>flags</code></em> have an effect similar
to installing default handlers for the widget's drag-and-drop signals
(<span class="type">"drag-motion"</span>, <span class="type">"drag-drop"</span>, ...). They all exist
for convenience. When passing <a class="link" href="gtk-Drag-and-Drop.html#GTK-DEST-DEFAULT-ALL--CAPS"><span class="type">GTK_DEST_DEFAULT_ALL</span></a> for instance it is
sufficient to connect to the widget's <a class="link" href="GtkWidget.html#GtkWidget-drag-data-received" title='The "drag-data-received" signal'><span class="type">"drag-data-received"</span></a>
signal to get primitive, but consistent drag-and-drop support.
</p>
<p>
Things become more complicated when you try to preview the dragged data,
as described in the documentation for <span class="type">"drag-motion"</span>. The default
behaviors described by <em class="parameter"><code>flags</code></em> make some assumptions, that can conflict
with your own signal handlers. For instance <a class="link" href="gtk-Drag-and-Drop.html#GTK-DEST-DEFAULT-DROP--CAPS"><span class="type">GTK_DEST_DEFAULT_DROP</span></a> causes
invokations of <a
href="/usr/share/gtk-doc/html/gdk/gdk-Drag-and-Drop.html#gdk-drag-status"
><code class="function">gdk_drag_status()</code></a> in the context of <span class="type">"drag-motion"</span>,
and invokations of <a class="link" href="gtk-Drag-and-Drop.html#gtk-drag-finish" title="gtk_drag_finish ()"><code class="function">gtk_drag_finish()</code></a> in <span class="type">"drag-data-received"</span>.
Especially the later is dramatic, when your own <span class="type">"drag-motion"</span>
handler calls <a class="link" href="gtk-Drag-and-Drop.html#gtk-drag-get-data" title="gtk_drag_get_data ()"><code class="function">gtk_drag_get_data()</code></a> to inspect the dragged data.</p>
